Hydraulic modeling is seldom used in the day-to-day design of closed-loop or open-loop heating and cooling systems.

Engineers who pull out the 2015 ASHRAE Handbook HVAC Applications or 2016 HVAC System and Equipment Handbook will not find the topic of temporary HVAC systems.

Years after an HVAC engineer starts to design closed-loop water systems and then progressively moves up the ladder of engineering success, he can forget and/or overlook many of the issues, concerns, details, opportunities, etc. associated with engineering these systems.

With last month’s publication, Engineered Systems magazine and I completed the 25th year of publishing this column.

How often does an existing open condenser water system, or some other type of open water system, get reused as part of a building renovation project and/or mechanical system upgrade

How often does an existing closed loop hot water heating or chilled water cooling system get reused as part of a building renovation project, and/or used to expand the area served by the system coverage to provide additional heating or air conditioning?

This month, the focus is on high-performance health care, and so it got me thinking about IAQ and infection control (IC) within hospi-tals.

This month’s B2B will focus on an 80,000-sq-ft existing commercial office building in need of replacing its two air-cooled chillers.

This past August, I wrote in this column about the opportunity to invest in a niche business providing temporary HVAC design and construction administration.

This month’s B2B will focus an existing campus administration building renovation.
